COOLER.

of California., have linvented new and useful" Improvements in` Coolers, ofwhich the following is a specification.

This invention relates to improvements in coolers, particularly to the class of portable coolers for refrigerating purposes, the present inventionbeing an improvement on the cooler described and claimed in the-Letters Patent of the Unitedl States #1,138,505 granted tome on May 4*, 1915'. Y

One object of the invention is to eect improvements in theV construction ofthe top of the body ofthe cooler and which also forms the bottom of the tank or reservoir.

Another object is to provide valves to regulate the escape of water from the tank.

Another object is to provide the wall sections of the body with a drip channel near their upper ends. i

The invention consists in the features of construction, combination, andarrangement of devices, hereinafter fully described and claimed. v

In the accompanying drawings Figure 1 is a vertical sectionalview of a cooler constructed and arranged in accordance with my invention.

Fig. 2 is a horizontal sectional view of the same.

Fig. 3 is a detail sectional view.

Fig. 4 is a detail top plan view of the door.

Fig. 5 is a detail vertical sectional view through the top and the contiguous upper portion of the wall.

Fig. 6 is a detail top plan view.

The vcooler comprises a body 1 and a tank or water reservoir 2. The body comprises a bottom 3, a top 4 anda wall 5, and together with the tank is preferably made of cement. The bottom is circular and is provided with anannular groove or channel 6 in its upperv Specification of Letter'slatent.

bottom v3 anda suitable flexible lhose 6b may be attached tothe lowerv` end of the nipple;

to. carry off the overiiow waterv from the channel to a suitable place.

vEach wall section'is formed of a flange 10 on its outer side nearits upper end which e latented Ofct. 2', 191.7'. Application filed August s, 1916. serial No. 113,788.y

projects i outwardly'therefrom and in the y upper side of which is a water channel 11. Thelelement 4 which forms the top of the body `and also forms the bottom of the tank 2 has a groove 12l in its lower side which receives the upper edge of the wall V5. The

extreme diameter of the element 4 is greater l than that .ofv the body, so that said element 4 projects outwardly tol forni a ledge 18 which extends around the body.L Said ledge is provided| at points-below the discharge valvesQl of the tank 2-with basins 14 which are scooped therein and is alsoprovided with notches 1 4a inthe outer walls of saidV basins for theescape of'water'v therefrom,

said notches leading downwardly and said element 4 having downwardly and inwardly inclined surfaces 15 betweensuch notches to assist in conducting the water to the channel or gutter 11. Said gutterV or channelv overflows, so that water passes therefrom downwardly over the iiange 10 and spreads over the outer surface of the wall 5 keeping such surface wet and such water as does not evaporate on the outer surface of the wall, finally reaches the lower gutter or channel 6.

To increase the superficial area of the wall 8 and cause maximum evaporation on the moistened outer surface thereof, I coat the outer surface of the wall sections, while the cement mortar, of which they are composed, is in a plastic state, with dry sand, which becomes cemented on' and becomes a. perfect surface for spreading the water on the wall and to promote the evaporation of the water thereon.

The door 9 is provided with a channel 9a ends, outwardly as at 9b and the outer wall of said channel is also formed with notches 9c. The wall section in which the door is `hinged and which forms the frame for the door, is provided with notches 9d to conduct water to such `channel 9L as will be understood.

The tank 2 comprises an integral top 16 and a wall 17. The top is provided with a hole 18 to enable water to be supplied to the tank and a stopper 19 may be provided for Vin its upper edge, and which opens, at the A such hole. The lower edge of the wall 17 fits closely on the sloped upper surface of the element 4, which element forms the bottom of the tank as well as the top of the body of the cooler. Four, or any other suitable number of pipes 20 which may be constructed of lead and which are of very slight diameter, preferably of about a quarter of Sockets 23, 24, are arranged in the centers of the bottom and top of the body as shown. The socket 24 receives the upper end of al lrod 25 said rod has a plug 25EL at the lower end which bears in the socket 23. Said rod carries and permits the rotation of a suitable number of disklike shelves 26. i Each of said'shelves has a centrally arranged sleeve 27 through which the rod eX- tends and said sleeve has a set screw 27a.

' Hence the shelves may be vertically adjusted on the rod as desired. The shelves being rev- ,oluble, enable food products to be readily placed thereon or removed therefrom through the door. The shelves and other concrete portions of the cooler are in practice reinforced.

Having described the invention, what is claimed is:

l. A cooler of the class described comprising a body, a tank thereon, an element forming the top of the body and also forming the bottom of the tank and projecting out beyond the sides of the body, the projecting portion of said element having basins in its upper side and notches in the' outer walls of said basins for the escape of water therefrom, water outlets lfor said tank and discharging in said basins.

2. A cooler of the class described comprising a body, a tank thereon, an element forming the top of the body and also form-l ing the bottom of the tank and projecting beyond the -sides ofthe body, and valved water outlets for said tank, the said element having a downwardly and outwardly sloped outer portion, and a downwardly and inwardly sloped under surface upon the projecting portiomandthe bodyof the cooler being provided on its wall with an exteriorly arranged flange spaced below the outer edge of said element and having a channel for the reception of water therefrom.

In testimony whereof I afHX my signature.
